Overview
The KNPB-48 48 Ports PoE Switch is a high-performance managed switch series designed for large edge deployments that require centralized management of many distributed access devices. It integrates SmartMC (Smart Management Center) for unified operation and maintenance, and supports rich IPv4/IPv6 L3 features, multi-tunneling, multicast, policy routing, and advanced QoS and security controls.

SmartMC (Smart Management Center)
SmartMC centralizes the management of many scattered network devices and simplifies switch-based O&M tasks for small and medium networks.

• Intelligent management: device role selection, FTP server configuration, global configuration, network management port configuration.
• Intelligent operation and maintenance: group management, device/group upgrade and backup, monitoring and device failure replacement.
• Visualization: network topology visualization, device list display.
• Smart business: user management and one-key port arming to enable network access for created/activated users.

High performance IPv4/IPv6 capabilities
KNPB-48 implements a hardware-based IPv4/IPv6 dual-stack platform, supports multiple tunneling technologies, rich IPv4/IPv6 layer-3 routing protocols, multicast technologies and policy routing mechanisms to provide a complete IPv4/IPv6 solution.

IRF2 (Second Generation Intelligent Resilient Architecture)
KNPB-48 supports IRF2 to virtualize multiple physical devices into a single logical device for unified management and higher resilience. Benefits include:

• Simplified management: single logical device login and configuration for all member devices.
• Simplified service behavior: control protocols run as one device; supports cross-device link aggregation and reduces protocol packet exchanges.
• Elastic expansion: flexible capacity expansion, hot-swap join/leave of devices without impacting other devices.
• High reliability: multi-link backup, automatic master election for device-level 1:N backup, real-time protocol hot backup across member devices.
• High performance: aggregate performance and port density across IRF member devices.

Security and access control
The series supports EAD (End Access Control) integrated with backend systems to combine terminal security (antivirus, patch repair) and network security (network access control) into a linked security system to inspect, isolate, repair and monitor network access terminals, shifting from passive to active defense.

• Centralized MAC address authentication, 802.1x authentication, PORTAL authentication.
• Dynamic/static binding of user identifiers: account, IP, MAC, VLAN, port, etc.
• Dynamic distribution of user policies (VLAN, QoS, ACL).
• Support for real-time online user management and illegal behavior diagnosis via management systems.
• Enhanced ACL control logic: super-capacity ingress/egress ACLs, VLAN-based ACL delivery, support for uRPF (unicast reverse path forwarding) to prevent source address spoofing.

Reliability and redundancy
KNPB-48 provides multiple device-level and link-level reliability features:

• Pluggable AC and DC dual power supply module support (flexible AC/DC module configuration).
• Power and fan fault detection and alarm.
• Link-level protection: LACP, STP/RSTP/MSTP, Smart Link, RRPP fast ring protection, IRF2, 1:N redundant backup, ring stacking, cross-device link aggregation.

Quality of Service (QoS)
Comprehensive QoS features from L2 to L4 packet filtering and flexible queue scheduling:

• Classification based on source/destination MAC, source/destination IP, TCP/UDP port, protocol type, VLAN.
• Queue scheduling: SP, WRR, SP+WRR; CAR (Committed Access Rate) with minimum granularity 16 Kbps.
• Support for inbound/outbound port mirroring for monitoring and troubleshooting.

Management and monitoring
Rich management interfaces and protocols:

• Console port, out-of-band management port.
• SNMP v1/v2/v3 support; compatible with network management platforms (OpenView, iMC).
• CLI, Web management, TELNET, SSH2.0 and encrypted management methods.
• SPAN/RSPAN mirroring and multiple mirroring observation ports; network flow analysis reporting.
